Free CAD software you can use online
TextoCAD is free AI CAD software that runs in your browser. Describe a part in plain English, get an editable parametric model, and export STEP or STL for free. No install, no upfront cost.
Free online CAD without the learning curve
Most free CAD programs are powerful but hard to learn, and many ask you to download and install a large application. TextoCAD takes a different approach. It is free CAD software that runs online in the browser, and you create models by describing them in plain English instead of learning a complex interface.
You can generate a part, tune its dimensions with sliders, and export it without paying. That makes it a practical free online CAD option for students, makers, hobbyists, and engineers who want a fast starting point.
What stays free
Describing parts, generating editable models, adjusting parameters, saving projects, and basic STL and STEP export are free to use. Paid plans are optional and only unlock a more powerful AI model and higher monthly limits for heavier or more complex work.
Why it is free and online
Free to use
Describe, generate, edit, and export CAD models in your browser without paying. No trial countdown to use the core workflow.
Nothing to install
Runs fully online in any modern browser. No download, no license file, no heavy workstation needed.
Editable parametric models
Every model exposes its dimensions as live sliders, so you keep full control after generation.
Free STEP and STL export
Download STEP for CAD and engineering, or STL for 3D printing. Basic export is free.
AI assistant
Refine your design by chatting in plain English instead of learning complex CAD commands.
Optional upgrades
Paid plans are optional. They only unlock a more powerful AI model and higher monthly limits for heavier use.
How free online CAD with AI works
TextoCAD is built on the same engine as our text to CAD and AI CAD generator pages. You write a prompt, the AI generates a parametric model, and you refine it. If you prefer a browser CAD tool with no install for general use, see online CAD.
Frequently asked questions

Yes. TextoCAD is free to use online. You can generate CAD models from text, edit them with sliders, and export STEP and STL files without paying. Paid plans are optional and only add a more powerful AI model and higher monthly limits.
Is it free CAD software with no download?
Yes. TextoCAD is browser based, so there is nothing to install. Open the editor, describe your part, and start designing online for free.
What can I do with the free version?
You can describe parts in plain English, generate editable parametric models, adjust dimensions with sliders, save projects, and export STEP and STL files. Slider edits and basic exports do not consume credits.
What do paid plans add?
Paid plans are optional. They unlock a more powerful AI model for complex designs and raise your monthly generation limits. The core free workflow stays available.
Can I use it for 3D printing for free?
Yes. Generate a model from text, set the dimensions you need, and export a free STL ready for your slicer. See the text to STL guide for the full workflow.
